A case is presented in which primary hyperoxaluria and oxalosis in a 14-year-old Caucasian female were diagnosed. Generalized root resorption resulted in a remarkable mobility of her maxillary central and lateral incisors, although no bone loss was noted. The management of the patient's dental concerns in this rare heritable metabolic disorder consisted of removing the maxillary incisor teeth and placing two sequential prostheses, which the patient tolerated well. A history of trauma to the maxillary incisors was ruled out, so this case adds previously unreported information to our knowledge about the effect of oxaluria on teeth and oral tissues.
